Research on the longitudinal roll stabilization of the KU ship ,,Mintis” in the Master's Thesis. The paper reviews research, examines the theory of longitudinal support of ships, longitudinal torsion of multi - hull ships and the improvement of marine properties. In the first part of the Master‘s Thesis work the scientific analysis is performed, which is aimed at finding out the answers to the questions related with the pitching and the heaving as well as the analysis of the factor which have influence over that marine features being carried out. In the second part of work the linear theory of the catamaran pitching and heaving, the theory comprising formulas and their components are being analysed. In the part of this work more precise formulas of the vessel pitching and heaving are recorded, on the basic of which mathematical pitching and heaving experiments are being carried out. In the next part, longitudinal torsion calculations are performed, and the experiment is described. Calculations are performed on the basis of linear ship roll theory and using the calculated fluid dynamics program ,,FLOW – 3D”. In the last part, the results are systemized and analysed as well as they are being compared between. Efficiency of applied underwater fins is analysed. |
